I assume you never use a bank ATM or a debit card at the grocery. It is becoming more and more common to see electronic devices used widely in public used by hundreds of people daily.
This takes it to the next level.
And I wonder how often the touch screens are cleaned and with something like bleach which is typically used in a fast foot rest for the counters, table tops and floors and bathrooms.
So the touch screens may get cleaned even less or not at all; never.
And the person who is not hygienically inclined and just used the rest room, has an infection like hep A... well yuck!
